The pressure inside your intake manifold is extremely important input to the ECU—so a quality MAP sensor (manifold absolute pressure) from Sierra Marine is crucial to your engine's performance. These replacement sensors will respond to changes in manifold pressures and relay the information to the ECU in the form of a voltage signal. They are manufactured with quality materials that will meet or exceed OEM specifications. Order the model recommended for your marine engine application.
